Amnesia (from Greek Ἀμνησία) is a condition in which memory is disturbed or lost. The causes of amnesia can be organic or functional. Organic causes include damage to the brain through trauma or disease or the use of certain (generally sedative) drugs. Functional causes are psychological factors, such as defense mechanisms. Hysterical post-traumatic amnesia is an example of this. Amnesia may also be spontaneous, in the case of transient global amnesia. This global type of amnesia is more common in middle-aged to elderly people, particularly males, and usually lasts less than 24 hours. Memory loss can be partial or total and is normally expected as we get older. | |||

Overview
Amnesia (from Greek Ἀμνησία) is a condition in which memory is disturbed or lost. The causes of amnesia can be organic or functional. Organic causes include damage to the brain through trauma or disease or the use of certain (generally sedative) drugs. Functional causes are psychological factors, such as defense mechanisms. Hysterical post-traumatic amnesia is an example of this. Amnesia may also be spontaneous, in the case of transient global amnesia. This global type of amnesia is more common in middle-aged to elderly people, particularly males, and usually lasts less than 24 hours. Memory loss can be partial or total and is normally expected as we get older.
